ARINSO was founded by Jos Sluys in 1994 and ended 2007 with total sales of 204 million euro and more than 2,500 staff in 27 countries. ARINSO International was floated on Euronext Brussels in 2000 (ticker: ARIN) and listed on LSE as part of Northgate Information Solutions plc (ticker: NIS) until March 2008. In December 2007, private equity fund KKR launched a take-over bid on NorthgateArinso, valuing the group at 593 million £ (approximately 780 million euro), after which the company was delisted and taken private.
